Yup. When I was 16-17 I’d be going out with friends all the time and almost never stuttered. I graduated early and went to a small college where no one talks to anyone else so I had no friends. As time went on my stutter came back and got worse then Covid hit and now my stutter is worse than it’s ever been. I think that the more you talk, the less you stutter. Confidence is involved as well but you get more confident in yourself and in your speech the more often you talk to people
